This commit introduces a notion of different styles for the formatting
of Duration.
The `@DurationFormat` annotation is added to ease selection of a style,
which are represented as DurationFormat.Style enum, as well as a
supported time unit represented as DurationFormat.Unit enum.
DurationFormatter has been retroffited to take such a Style,
optionally, at construction. The default is still the JDK style a.k.a.
ISO-8601.
This introduces the new SIMPLE style which uses a single number + a
short human-readable suffix. For instance "-3ms" or "2h".
This has the same semantics as the DurationStyle in Spring Boot and
is intended as a replacement for that feature, providing access to the
feature to projects that only depend on Spring Framework.
Finally, the `@Scheduled` annotation is improved by adding detection
of the style and parsing for the String versions of initial delay, fixed
delay and fixed rate.

Prior to this commit, the "Method Arguments" documentation for WebFlux
in the reference manual stated that WebFlux controller methods can
accept arguments of type Map, Model, or ModelMap to access the model.
However, ModelMap is actually not supported and results in exception
due to a type mismatch.
This commit updates the documentation to reflect this.
In addition, this commit updates related Javadoc and tests to avoid
mentioning or using ModelMap in WebFlux.

Prior to this commit, `@ExceptionHandler` annotated controller methods
could be mapped using the exception type declaration as an annotation
attribute, or as a method parameter.
While such methods support a wide variety of method arguments and return
types, it was not possible to declare the same exception type on
different methods (in the same controller/controller advice).
This commit adds a new `produces` attribute on `@ExceptionHandler`; with
that, applications can vary the HTTP response depending on the exception
type and the requested content-type by the client:
```
@ExceptionHandler(produces = "application/json")
public ResponseEntity<ErrorMessage> handleJson(IllegalArgumentException exc) {
return ResponseEntity.badRequest().body(new ErrorMessage(exc.getMessage(), 42));
}
@ExceptionHandler(produces = "text/html")
public String handle(IllegalArgumentException exc, Model model) {
model.addAttribute("error", new ErrorMessage(exc.getMessage(), 42));
return "errorView";
}
```
This commit implements support in both Spring MVC and Spring WebFlux.

If multiple request mapping annotations are discovered, Spring MVC and
Spring WebFlux now log a warning similar to the following (without
newlines).
Multiple @RequestMapping annotations found on
void org.example.MyController.put(), but only the first will be used:
[
@org.springframework.web.bind.annotation.PutMapping(consumes={}, headers={}, name="", params={}, path={"/put"}, produces={}, value={"/put"}),
@org.springframework.web.bind.annotation.PostMapping(consumes={}, headers={}, name="", params={}, path={"/put"}, produces={}, value={"/put"})
]

This commit extract spring-related links and recurring external links
into asciidoctor attributes to be used by the Antora toolchain.
It notably homogenizes links to:
- IETF RFCs
- Java Community Process JSRs
- the Java API Documentation (on the Java 17 version)
- Kotlin documentations (on the Kotlinlang.org version)
- the Spring Boot reference guide (on the `html` version)
This commit also reworks most link attributes to follow a
Project-Category-Misc syntax. For example, `spring-boot-docs` rather
than `docs-spring-boot`.
Finally, it makes an effort to clean up remainders from the previous
documentation toolchain, namely the `docs/asciidoc` folder and
`modules/ROOT/pages/attributes.adoc` file.

Previously the documentation assumed that the readers knew how to use
the X-Forwarded-* headers. This commit documents details & examples
of how to use the X-Forwarded-* headers.

BlockingExecutionConfigurer#setExecutor takes an AsyncTaskExecutor
not an Executor as the documentation states. With this commit,
this has been corrected.
